I installed passcal.2010.233.x86_64.tar on Fedora 14 and Centos5 and logpeek fails on both trying to import TKinter.
Installing PQL-2010-246.x86_64.rpm on Fedora14, pql runs with a bunch of error messages maybe because the libraries are all 32-bit . Centos5 refuses to run pql because the libraries don't match.
